Answer:
A eukaryote is an organism with complex cells, or a single cell with a complex structures. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all eukaryotes. There are also eukaryotes amongst single-celled protists.
Answer:
A gene mutation can be described as errors in the nucleotide sequence of a gene due to errors in the DNA replication process or due to any mutagen. On the other hand, a chromosomal mutation can be described as a change in the structure of a DNA or changes in the number of chromosomes.
A gene mutation occurs in a single gene whereas a chromosomal mutation will affect many genes. Hence, gene mutations will be comparatively less lethal than chromosomal mutations.
Example of gene mutation: Sickle cell anemia
Example of chromosomal mutation: Down's Syndrome
